Bảo toàn khối lượng :
\(m_{O_2}=44.6-28.6=16\left(g\right)\)
\(n_{O_2}=\dfrac{16}{32}=0.5\left(mol\right)\)
Bảo toàn O :
\(n_{H_2O}=2n_{O_2}=2\cdot0.5=1\left(mol\right)\)
Bảo toàn H :
\(n_{HCl}=2\cdot n_{H_2O}=2\cdot1=2\left(mol\right)\)
\(V_{dd_{HCl}}=\dfrac{2}{1}=2\left(l\right)\)
Bảo toàn khối lượng :
\(m_{Muối}=44.6+2\cdot36.5-1\cdot18=99.6\left(g\right)\)
\(n_O=\dfrac{44,6-28,6}{16}=1\left(mol\right)\)
\(n_{HCl}=n_{Cl^-}=n_O=2\left(mol\right)\)
\(m_{muối}=m_{KL}+m_{Cl^-}=28,6+2.35,5=99,6\left(g\right)\)
\(V_{HCl}=\dfrac{2}{1}=2\left(l\right)\)
